If I remember correctly, good old Col. Cooper had a popular quote on that subject; I think it was
"Owning a handgun doesn't make you armed any more than owning a guitar makes you a musician."
And that reminds me of an old joke (which also seems to apply here):
NYC Tourist: "Excuse me, do you know how to get to Carnegie Hall?"
New Yorker: "Yeah; practice, practice, practice..."
